Analysis of Fractional Frequency Reuse (FFR) over Classical Reuse Scheme in 4G (LTE) Cellular Network
Abstract: With the advent of fourth generation (4G) cellular networks like Long Term Evolution (LTE), there is always difficulty for proper frequency planning as it is targeting aggressive spectrum reuse (frequency reuse 1) to achieve high system capacity (rate and throughput). At same time, we face signal degradation at cell edge users due to interference by co-channel cells. There are various ways to manage interference by co-channel cells. This paper is focus on comparison of Fractional Frequency Reuse (FFR) over classical reuse scheme on basis of probability of acceptance rate with respect to Rate Threshold. And in order to allocate resources in Cells, Signal to Interference plus Noise Ratio (SINR) proportional resource allocation strategy is deployed. We observe that FFR provides better acceptance rate as well as improved coverage for cell edge users in LTE environment.
